Description

Scrap coil drawing device {Device for leading scrap coil}

The present invention relates to a scrap coil winder for winding a scrap portion of a strip generated by a stainless annealing process into a coil, and to remove the coil when the scrap coil is removed from the winder. Relates to a device.

In general, hot rolled strips are finished by hot-rolled coils through annealing rinse lines. As a result, various defects are generated in the strips, and in particular, defects are concentrated in the front and rear ends of the strips. Will be processed separately.

In this way, the scrap which is cut from the strip and processed separately is sent to a winding machine to be wound in a coil form for processing.

However, since the length of the scrap is usually very short, about 10-15m, the winding was not properly made and there was a problem that the coil was unwound.

That is, as shown in FIG. 3, when the coil 150 is completely wound on the side mandrel 101 of the winder 100, the coil 150 is removed by removing the coil 150 from the mandrel 101. In order to convey the coil 150, the scrap is closed when the mandrel 101 is reduced and the hold down roll (not shown) pressed against the upper part of the coil 150 is pulled out. The coil will loosen.

Therefore, in the related art, as illustrated in FIG. 3, the pipes 110 are sandwiched between the rolls 104 and the coils 150 of the coil car 103 to prevent the coils 150 from being loosened, or the material may be a thick plate. In this case, the coil was further wound around a certain length to prevent the coil from loosening.

However, the above-described conventional structure has a high possibility of causing injury and takes a lot of drawing time due to unstable operation, and in the case of thick plates, normal products are treated like scrap coils, resulting in unproductive and inefficient performance.

Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a scrap coil withdrawal device that can prevent the source of loosening by pulling out the scrap coil mechanically.

In order to achieve the above object, the present invention includes a gripping portion for gripping a scrap coil and a moving portion for moving the gripping portion to the outside of the mandrel.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a scrap coil extraction apparatus according to the present invention, Figure 2 is a view schematically showing a state of use of the extraction apparatus according to the present invention.

According to the above drawings, the moving part according to the present invention rail 10 is installed to the side of the mandrel 101 of the winder 100 on the floor of the installation, the wheel 21 in the lower portion to be moved along the rail 10 The trolley 20 is installed, the rail member 30 is placed in the width direction of the mandrel 101 on the trolley 20, the wheel 41 is placed on the rail member 30 in the lower rail member ( Moving member 40 is horizontally moved along the 30, it is fixed to the trolley 20 and is connected to the moving member 40 consists of a drive cylinder 42 for pushing and pulling the moving member 40.

Here, the moving member 40 moves forward toward the mandrel 101 out of the trolley 20, at which time the rail member 30 of the trolley 20 supports the moving member 40 with respect to the trolley 20. The T-shaped plate 43 is installed therebetween, and the T-slot member 44 fitted to the T-shaped plate 43 is installed on the bottom surface of the movable member 40 so as to be engaged with each other and slide.

The gripping portion is installed on the upper portion of the moving member 40, the vertical bracket 50 is installed vertically on the left and right sides of the mandrel 101 side of the moving member 40, and the upper and lower portions of the vertical bracket 50, respectively Rotating shafts 51 and 53 to be installed, the upper rotary shaft 51 is fixedly installed at both ends and the end of the upper grip member 52 is bent downward, the lower rotary shaft 53 is fixed to the both ends of the lower grip end is bent upwardly The upper and lower rotary shafts 51 and 53 are rotatably connected between the member 54 and the upper and lower rotary shafts 51 and 53. The operating member 55 protrudes upward from the center portion and the operating member 55 and the movable member 40. ) Consists of up and down operating cylinders 56 and 57 for rotating.

In addition, the mounting bracket 58 is installed vertically in the rear of the moving member 40, and the operation cylinders 56, 57 are installed in the horizontal state above and below the mounting bracket 58 so as to be rotatable in a horizontal state.

Here, the lower gripping member 54 extends a predetermined length further toward the mandrel 101 than the upper gripping member 52, and the guide roll 59 is installed between the ends, and the scrub coil 150 is inserted into the mandrel 101. ) Make sure to contact the bottom smoothly.

In addition, since the inner surfaces of the upper and lower holding members 52 and 54 come into contact with the scrap coil 150, the curved surface is smoothly curved in an arc shape.

Meanwhile, the weight 60 is installed at the rear of the moving member 40 to compensate for the weight when the scrap coil 150 is gripped by the front holding members 52 and 54.

Hereinafter will be described the operation of the present invention.

When the scrap coil 150 is generated, the trolley 20 moves to the side of the mandrel 101 along the rail 10 placed outside the mandrel 101.

When the truck 20 reaches the working position, the operator contracts and operates the upper operation cylinder 56 and the lower operation cylinder 57 of each of the operation cylinders 56 and 57 installed on the moving member 40. Operate to widen the gap between the upper and lower gripping members (52, 54) more than the diameter of the scrap coil 150.

That is, when the upper operation cylinder 56 is contracted and operated, the operating member 55 installed on the upper side of the rotating shaft 51 is pulled to rotate the rotating shaft 51, so that the upper holding member 52 installed on the rotating shaft 51 is upward. Will be lifted. Similarly, the lower rotating shaft 53 is rotated in accordance with the extending operation of the lower operation cylinder 57 to rotate the lower holding member 54 downward.

In this state, when the operation cylinders 56 and 57 are stopped and the driving cylinder 42 is extended and operated, the moving member 40 connected to the piston rod end of the driving cylinder 42 becomes the rail of the upper portion of the trolley 20. It moves along the member 30 toward the mandrel 101.

Here, the upper and lower gripping members 52 and 54 provided at the front side of the moving member 40 are wide enough to allow the scrap coil 150 to be inserted therein so that the moving member 40 is not prevented from proceeding. When the moving member 40 completely enters the mandrel 101, the holding members 52 and 54 are positioned above and below the scrap coil 150.

At this time, since the moving member 40 is moved, the T-slot member 44 under the moving member 40 slides in engagement with the T-shaped plate 43 of the trolley 20, so that the moving member 40 moves on the trolley 20. Even if it proceeds to the outside will not be separated from the trolley 20.

Next, when the upper operation cylinder 56 is extended and the lower operation cylinder 57 is contracted and operated, the upper and lower gripping members 52 and 54 are tightened, and the scrap coil 150 is inserted into the mandrel 101. Is held in the width direction.

When the scrap coil 150 is gripped, the mandrel 101 is reduced and the cart 20 is retracted so that the scrap coil 150 held by the gripping member can be pulled out of the mandrel 101. will be. At this time, the weight 60 of the scrap coil 150 is in charge of the weight 60 installed in the rear of the movable member 40, the movable member 40 can maintain the balance.

The drawn scrap coil 150 is scraped by bending in a post process, and the moving unit and the trolley 20 are repositioned for the next operation.

According to the scrap coil extracting apparatus according to the present invention as described above, it is possible to prevent the coil unwinding phenomenon by holding the scrap coil in the width direction and withdraw. In addition, it is possible to prevent human injury or equipment accidents that occur when the coil is loosened.
